carbondata git commit: [CARBONDATA-2916] Add CarbonCli tool for data
summary
Repository: carbondata
Updated Branches:
refs/heads/master 055b7a784 -> c40d85478
[CARBONDATA-2916] Add CarbonCli tool for data summary
A tool is added to print information of a given data folder
usage: CarbonCli
-a,--all print all information
-b,--blocklet print blocklet size detail
-c,--column <column name> column to print statistics
-cmd <command name> command to execute, supported commands are:
summary
-h,--help print this message
-m,--showSegment print segment information
-p,--path <path> the path which contains carbondata files,
nested folder is supported
-s,--schema print the schema
-t,--tblProperties print table properties
This closes #2683
